PLATE-HOLDER FOR PHOTOGRAPHERS.

.SPECIFICATION forming part of Letters Patent No. 373,231, dated November 15, 1887. Application iiled July 16, 1887. Serial No. 244,488. (Model.)

To all whom, it may concern.-

Beit known that I, WILLARD H. FULLER, of Passaic, in the county of Passaic and State of New Jersey, have invented a certain new and useful Improvement in Plate-Holders for Photographers Use, of which the following is a specification.

I will describe in detail a plate-holder embodying my improvement, and then point out the novel features in the claims.

In the accompanying drawings, Figure l is a side -view of a plate-holder embodying my improvement, one of the'shutters being partly withdrawn. Fig. 2 is a similar view showing an adjustable section or end piece of the frame in a diderent position. Fig. 3 is a longitudivnal section taken at the plane of the dotted line x x, Fig. l, and showing one of two ad` justable end pieces or end sections in its normal position and the other in a reverse position. Fig. 4 is a transverse section.

Similar letters of reference designate corresponding parts in all the figures.

A designates the frame 'of the holder. It is composed of two parallel pieces, a a2, and two intermediate pieces, as a, extending at right angles to the pieces a a2. At about the center a diaphragm, c5, is arranged. The pieces a3 a4 of the frame I call the end pieces. The end piece a4 isnot so thick as the other pieces of the frame, and has combined with it adjustable end pieces a6 al, arranged one on each side of it. The end piece a4 and the adjustable end pieces a6 a7 together approximately equal the thickness of the opposite end piece, a3.

The pieces aa.2 and the end piece a3 are provided with grooves as a, arranged one on each side of the diaphragm a5, and the adjustable end pieces a a7 are provided with corresponding grooves. Sliding shutters Bv B2 may be fitted within these grooves. They may be inserted through the end piece a3, the grooves asa being extended through this end piece to ad mit of this. The shutters are provided with hand-pieces, by which they may be manipulated.

The adjustable end pieces dal are provided at the end with tongues b, which enter grooves 5o c, formed in the opposite faces of the end portions ofthe pieces a a2. The tongues b are provided with shoulders b at the inner ends.

C designates bars or plates, which, as here shown, are fitted into recesses into one end of the pieces a a. They are secured in place by means of screws c. Theyextend across the shoulders b of the tongues b and prevent the adjustable end pieces dal from being adjusted too far out.

Each side of the diaphragm c5 is provided with a spring, am. side of the diaphragm of suitable size for containing a photographic plate. The plates will rest against the springs of the cavities. The end piece a3 of the frame of the plateholder is provided with flanges overlapping the cavities and adapted to secure within the same the adjacent ends of the photographic plates. The adjust-able end pieces c6 al are also provided with Iianges, and these flanges overlap and secure the other ends of the photographic plates when the adjustable end pieces are in their normal positions.

To remove the plates from the holder the shutters will be moved out and the adjustable end pieces moved as far outward as they are capable of being moved. Then the springs al will throw the released ends of the plates outwardly, so that they may be grasped by the ngers and taken out. When plates are to be inserted in the plate-holder, the adjustable end pieces will be moved outwardly as far as pos sible. The plates will be introduced into the cavities of the plate-holder and extended at one end under the flanges of the end piece as, after which the adjustable end pieces will be moved inward and the shutters closed.

D designates a lock consisting of a button which is pivotally connected to the outer surface of the end piece a, in the present instance by a screw, d, passing loosely through said button and engaging with the end piece. This button may be turned so that its length will coincide with the length of the end piece a. the adjustable end pieces a6 c", and hence will not interfere with their adjustment. After the adjustable end pieces a6 al shall have been adjusted as far inward as possible, so as to secure the photographic plates, the button D There isa cavity on each When thus adjusted, it will not overlap may be turned, so as to overlap the outer surfaces of the adjustable end pieces. Then the button will retain the adjustable end pieces in the position last described. Preferably the end piece at will be recessed and the button fitted into the recess. Vhen this expedient is resorted to, the outer surfaces of the adjustable end pieces will also be provided with recesses to receive the button. This construction will obviate the projection of the button beyond the end pieces a4 a a7.

The various pieces composing the frame ofthe plate-holder may be made of Wood. The diaphragm of the plate-holder may be made of Wood or binders7 board or analogous material. The shutters may be made ot' binders board and vprovided with hand-pieces made of Wood. The springs am, the bars C, and the button D may be made of brass or analogous material.

This plate-holder may be'made to contain only one plate, instead of a number of plates, if desirable. It is a very simple, cheap, and serviceable plate-holder,'and withal one capable of being very conveniently manipulated.

`What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a photographic-plate holder, the combination of fixed side pieces, a fixed end piece, a sliding end piece, and a stop for limiting the extent ofoutward movement of the sliding end piece, substantially as specified.

2. In a photographic-plate holder, the combination of fixed side pieces, a xed end piece,

a sliding end piece provided with shouldered pieoe in the position Which it is intended nor mally to occupy, substantially as specified.
